Descripció del contingut i pla d'activitats:
Barred galaxies, which are characterized by a central bar composed of stars, exhibit a notable dynamical behavior wherein the equilibrium points contribute to organizing the dynamics of the system. In some galaxies, such as the Large Magellanic Cloud, the bar is displaced from its central position, which results in a bifurcation of the equilibrium points. In classical models, where the bar is centered, the model has five equilibrium points with two of them exhibiting a saddle x centre x centre behavior (with realistic parameters of the galaxy) around which the arms of the galaxy emanate. The present study aims to investigate the bifurcations of the equilibrium points depending on the position of the bar and other parameters of the system. This would allow us to explain galaxies with different numbers of arms.
